UFC president Dana White is eager to showcase the WEC's fighters at 155 pounds and under to a larger audience on the UFC's higher-profile shows, putting every fighter under contract to the UFC's parent company under a single banner.

"What's exciting for these lighter-weight guys, they're finally on the biggest stage in the world now," White said. "A lot of people haven't seen the lighter guys, and when we move these guys up into the UFC, I think people are going to be glad to see them."

The merger will happen gradually in 2011, with every WEC employee moving over to work for the UFC, which has more than 200 fighters under contract.

"It's always been our goal to have every weight class," White said. "We're looking at taking everybody in right now. We like to have those divisions deep. We'll be bringing in more guys, too."

The UFC bought the WEC in December 2006 and ran it as a separate promotion, eliminating two higher-weight WEC belts in December 2008 but keeping overlapping lightweight titles. While the UFC does roughly one pay-per-view show per month, the WEC concentrated on lower-profile regional shows typically aired on the Versus channel, doing just one pay-per-view show.

White also announced the UFC will add four fight cards to Versus next year, but the elimination of the WEC actually reduces the number of free fights on cable television in 2011.

The UFC's non-pay-per-view shows air on Spike TV.

White cited MMA's continuing globalization as a prime reason behind the move. The UFC is attempting to put on shows in India, China and Mexico, and it hopes to attract the attention of those countries' fans and smaller fighters alike by presenting a single competitive league.

"Everybody wanted this to happen for the last couple of years now, but it was a timing thing," White said. "As we start to open up these other markets and start to do these things, it was time."

Aldo, the Brazilian featherweight champion, arguably is the WEC's top fighter. He has won 11 straight bouts, including eight in a row since joining the WEC in June 2008.

The WEC's biggest star in recent years has been Urijah Faber, the former featherweight champion who draws huge crowds to his West Coast fights. Faber is scheduled to make his bantamweight debut against Takeya Mizagaki next month, headlining the penultimate WEC show.
